DOOR FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 613,273, dated November 1, 1898.

Application filed April 2, 1896. Serial No. 685,857. (No model.)

To all whom it may concern:

Be it known that I, EDWARD A. HILL, a I citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Doors for Railway-Cars, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to certain new and useful improvements in doors for railwaycars which are designed more particularly for use in connection with the transportation of cereals and similarloose commodities in bulk, and more particularly to that general type of grain-doors which are described and illustrated in United States Letters Patent No. 479,070, granted to. me July 19, 1892, and in which the door is arranged to operate on vertical guide-rods at the side of the doorway.

The primary object of my invention is to provide suitable connections between the door and the door-posts, whereby the door can be easily operated without binding or catching; and a further object of the invention is to provide devices for connecting the door to the door-posts, which have a more or less limited lateral play,whereby the parts will not become broken or disarrangedif one end of the doorshould be elevated above the other end in raising or lowering, and whereby the door is prevented from binding on the guiderods on which it operates when in such aposition.

With these and other ends in View my invention consists of the peculiar construction and arrangement of parts hereinafter described, and illustrated in the accompanying drawings, in which Figure 1 is a sectional elevation of the inner side of a car, showing my improved door applied thereto and provided with attachments embodying my invention, the said door being in a closed position. Fig. 2 is a transverse sectional view-of the car, showing one of its doors open and in an elevated position; and Fig. 3 illustrates the attachments by means of which the door is connected to the guide-rods.

Referring to the drawings, in which like letters of reference denote corresponding parts in all of the figures, A designates a grain-door which may be of the usual or any suitable construction consistent with my invention, and it may be employed in connection with grain-cars or any other cars for which it is or may be adapted.

E designates the side posts of the doorway in the car which the door A is'adapted to close, and these side posts are provided with longitudinal grooves e to receive the guiderods D. These guide-rods are secured in the grooves in a suitable manner, and at the upper end each rod is bent inwardly and upwardly to form an offset, d, which terminates in an inward bend or recess for the reception of the eye of the pivot-pin hereinafter described.

At the upper corners of the door I provide socket-plates B, which are'secured to the door in any suitable manner and preferably on the inner side thereof. These plates are provided with sockets b of suitable form, which are adapted to receive the pivot-pins C and retain them in place when the plates are secured in position on the door. The pivotpins rest in sockets b and are provided with integral heads 0 on their-inner ends, and are looped at their outer ends to form eyes 0,

which are adapted to loosely surround the guide-rods D, so that said pivot-pins may slide on the guide-rods when the door is raised or lowered, the eyescthereof operating easily on the rods and partially within the grooves than the other the pivot pins will adjust themselves accordingly, so that the door will not bind upon the rods and become inoper -ative. Doors of this character are frequently of such weight and are handled in such a manner that one end thereof is raised at a mo When the door is raised 0 time until the eyes of the pivot-pins reach a position 011 the offset (Z, and when this is done with a door constructed in accordance with my present invention the pivot-pins slide laterally in their sockets and thereby avoid the danger of binding the guide-rods, breaking the pivot-pins, or disarranging the parts.

XVhen the door has been raisedinto an elevated position, it can be secured by suitable fastening devices F to the top of the car in a manner common in the art.

By this construction it will be observed that the operating parts of my invention, comprising the pivot-pins, the eyes on said pins, and the, guide-rods, are protected, from injury by means of the socket-plates B and the arrangement of the guide-rods D in the grooves of the door-posts, the eyes in said pivot-pins operating on said guiderods and in the grooves. The parts are therefore protected from injury by heavy articles, and they are so arranged as notto take up room in the car.

The pivot-pins have a certain freedom of motion in the sockets b, so that they may turn freely and easily and properly adjust themselves while the door is being raised into the elevated position shown in Fig. 2, and this loose arrangement of the pivot-pins also permits the same to move laterally of the door in the sockets whenever such lateral play becomes necessary.

Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is

1. The combination with a door, and the door-posts provided With grooves, of guiderods secured in said grooves, socket-plates on the door, and pivot-pins provided with eyes adapted to receive the guide-rods, said pivotpins being loosely secured in the sockets of the socket-plates and having a limited play laterally of the door, substantially as described.

2. The combination with a grain-door and door-posts provided with grooves therein, of guide-rods secured in the said door-posts, plates secured on the door and provided with sockets, and pivot-pins loosely arranged in said sockets, and looped to form eyes at their outer ends and adapted to surround the guiderods and operate Vertically on said rods and in the grooves in the door-posts, substantially as described.

3. The combination with a door, of vertical guide-rods secured on each side thereof, socket-plates on the upper corners of the door, pivot-pins loosely arranged in said sockets so that the pins may have a limited lateral play, said pins being provided on their outer ends with eyes adapted to loosely surround the guide-rods, substantially as described.
